Sp ecifieation 1.211;.2rovernent in Lasts, of which the followption, in connection with these- ,ing drawings, is a specification, like on the drawings representing like 2. The present invention relates toa reinforcing plate for a last socket, and is emin plate so constructed as to preae ooden body of the last from splits gitud inally under the strains of use. ther feiitnre of the invention is em- :1 means for protecting the last socket means of a thimble or bushing, and to construct the thirnble or bushing in such a manner as to overcome the tendency the of to wear loose and drop out of the g in accordance with theinvention, that portion of the last where the socket is formed is provided with a reinforcing plate set into the surface of the last, the said plate having bifurcated wings or extensions which project a general, longitudinal direction at both sides of the socket, so as to afford an external t for the wood, tending to prevent any thereof, and consequent splitting he material. The socket is also provided with a bushing which is firmly held in position by the reinforcing plate, it bein.

practicable to form the said bushing integra with said plate, although such construction is not essential tov the invention.

of the last to be fitted by the reinforcing plate is simplified, while-the surface of the. last is flat and unbroken.

As best shown in Fig. 2, the lateral strain of the jack pin which tends to split the last, and which comes, as indicated, where the material is thinnest and least capable of resisting such strain, is taken up by the inner edges of the bifurcating projecting portions of the reinforcing plate, thereby greatly The socket a is provided with a wear-resistin bushing; and, in the construction shown in ig, 1, the said bushing b is made a part of the reinforcing plate 6, it being practicable to stamp the entire piece from sheet metal, and afterwards turn it upto the sha e indicated,

In making up the reinforcing plate and socket in this way, the adjoining ed es of the blank, indicated by the reference otter b,

are located at one side of the socket, so that an tendency of the bushing to spread apart wil not be communicated laterally to the body of the last where the splitting strain is to be avoided. Such tendency to spread,.
